Bunch of errors when trying to add Pangolin to this 3D camera app

[crosswick]

Hi - I would like to use this existing app to get a point cloud stream from my Revopoint POP 3, and do some processing on it using Pangolin and Cilantro:

https://github.com/Revopoint/3DViewer

However each time I do a minimal inclusion of Pangolin in the relevant CMakeLists.txt of this project, I get a whole bunch of errors, like for instance:

In file included from /usr/local/Cellar/qt@5/5.15.10_1/lib/QtWidgets.framework/Headers/QDialog:                    ~~~~~~~~~~~~~~~~~~~~~~~~~^1:

:7:                     ~~~~~^7 :

Perhaps somebody could help me figure out what's going on here, please? Seems like some kind of Qt conflict. Or perhaps a matter of conflicting C++ standards?

Meanwhile it seems it may be a conflict between versions 5 and 6 of Qt on my system; still investigating

I'm sorry no-one had any suggestions for you on this. I hope you figured it out. Since this is quite old and very user / machine / version dependent, I'll close the issue out.
